Vehicle range: John's old '89 LeBaron has a 16-gallon gas tank and gets 18 mpg. The number of miles he can drive is a function of how much gas is in the tank. Assume this is a linear function. a. Write this relationship in function form. b. Determine the domain and range of the function in this context.
